Abstract
The invention aims to provide an explosive shock-resistant optical fiber connector plug. The problem that the current optical fiber connector for an igniter is easy to damage is solved. The explosive shock-resistant optical fiber connector plug comprises a plug shell and a pin component arranged in the plug shell, wherein the pin component comprises a ceramic pin and a tail handle arranged at the rear end of the ceramic pin; at least one sealing ring inserted into the shell of an adaptive socket and matched with the shell of the adaptive socket in a sealing way is arranged on the tail handle of the pin component. After the plug is plugged into the adaptive socket, good sealing can be formed between the tail handle and the shell of the adaptive socket through the sealing ring, so that the phenomenon that the optical fiber connector is damaged when impact air pressure instantaneously generated by ignition explosion leaks at the place where the plug and the socket are matched can be prevented, and the problem that the current optical fiber connector for the igniter is easy to damage is solved.
Description
Technical field
The present invention relates to joints of optical fibre field, has especially related to a kind of joints of optical fibre of explosion-proof impact and has inserted
Head.
Background technology
Light energy transmission is obtained for increasingly widely to apply with its advantage such as quick, accurate in all trades and professions.Example
Such as in some special dimensions, in the operation such as igniting blasting optical transport technology is just used.In prior art, for igniter
The joints of optical fibre be mostly that the major function of realization is the biography of system light energy using conventional ST type fiber optic connector assemblies
It is defeated, although can to realize lighting a fire, but such fibre-optic connector structure low intensity, especially do not possess sealing property, in system
After realizing detonation ignition function, plug with the contact of socket contact of the gases at high pressure produced by lighting a fire from connector assembly
Release at face, powerful impulsive force can cause connector assembly bindiny mechanism to damage, the plug and socket of connector assembly is separated
Deng failure phenomenon.Therefore, the current optical connector for igniter there are problems that flimsy.
The content of the invention
